STORED-PRESSURE MOTOR-STARTING nnvron,

To all, whom it may concern:

Beit known that I, EDWARD P. NoYEs, a

citizen of the United States,residing at Wine 'chester, in the county of Middlesex and State of Massachusetts, have invented ce'rtam new and useful Improvements in Stored-Pressure lowing is a specification. v

This invention relates. to starting-devices .for motor apparatus employing an internalcombustion prime motor and a secondary power-delivering motor of the steam-engine,

com ressed-air engine, or similar type.

T e object of theinvention is to dispense with,auxiliary en 'nes or auxiliary valveh as heretofore been found tion engines on the stored-pressure plan. In place of such auxiliaries make use of the fluid-receiving and power-delivering engine which is a part of the motor system itself,

and temporarily connect the shaft of this engine with the shaft of the internal-combustion motor and propel the latter under the impulse ofthe former by means of stored com ressed-air or other pressure-fluid used, in-t e power-delivering engine until'the internal combustion motor has assumed itsv own normal functions .and becomes self-running, whereupon the power-delivering engine.v

may; beudisconnected from the internal-combustion prime-motor and connected with the machinery. which it is intended to drive-under prime-motor.

The accompanying drawing shows in Figurellasectional view of an automobile Vehicle having a motive plant equipped with my- L improved stored-pressure starting arrange ments. Fig, 2-represents an axial section of 2 to motor 1 and also leads to an air-storage tank 5 whose inlet isequipped with a manually-operablestop-valve 6.
